The multi-sport Polar RCX5 will help you to optimise your training by measuring your heart rate and then adjusting your heart rate zones for each individual exercise session. To match your current physiological condition, your zones can be set higher or lower so you can get the most out of every session. The Polar RCX5 houses a GPS sensor to guarantee that the training computer can keep up with you, giving you more accurate mileage and pace information.

Sport profiles are stored on the RCX5 so you can switch between them, whether you're cycling, riding or running. It is also able to give your heart rate in water so you can even get the most out of your swimming. Polar have developed Race Pace to help you to control your speed so you can go on to reach your target time. You can feel as though you have a personal trainer taking you through each session by accessing endurance training programmes from polarpersonaltrainer.com and improve your training.
